Syphilitic aortitis ascending aortic aneurysm and aortic regurgitation on chest x-ray

The lateral chest x-ray shows fine mural calcification limited to an aneurysm of the ascending aorta (arrowheads). The arch and descending aorta have no calcifications. A focal calcification in the annulus near the left coronary ostium is present (arrow). The left ventricle is enlarged (dashed arrow). Image B is a magnified view of the aneurysm. The arrowheads highlight the aneurysm. The arrow highlights the calcification in the aortic annulus.
